The Life Scientific Folgen

Professor Brian Cox of Manchester University describes how he gave up appearing on Top of the Pops to study quarks, quasars and quantum mechanics. Although he describes himself as a simple-minded Northern bloke, he has acquired an almost God-like status on our TV screens; while the 'Cox effect' is thought to explain the significant boost to university admissions to read physics. He talks to Jim Al-Khalili about learning to be famous, his passion for physics and how he sometimes has difficulty crossing the road. In 2005 Brian was awarded a Royal Society Research Fellowship for his work on high energy particle collisions at CERN and elsewhere - an enviable academic achievement. In 2009, he was voted one of the sexiest men alive by People magazine. He has invented a new kind of celebrity - a scientist who's regularly snapped by the paparazzi.Brian wants everyone to be as excited as he is about the laws that govern our universe: the beautiful, counter-intuitive and often weird world of quantum mechanics that explains what happens inside the nucleus of every atom, right down at the level of those exotically named elementary particles - quarks, neutrinos, gluons, muons. Challenged by Jim to explain the rules of quantum mechanics in just a minute, Brian succeeds; while conceding that the idea that everything is inherently probabilistic, is challenging. Even Einstein found it difficult. Schrodinger's cat, or Brian Cox, for that matter, are simultaneously both dead and alive. That's a fact. What this is all means is another question. "Am I just an algorithm?" Brian asks. "Probably", says Jim. Producer: Anna Buckley.

Carol Robinson describes her remarkable journey from leaving school at 16 to work as a lab technician at Pfizer, to becoming the first female Professor of Chemistry at both Oxford and Cambridge University, despite an eight year career break to bring up three small children.Getting back into the workplace wasn't easy. Carol was hired for a job for which she was over-qualified because she 'used to be good' and advised not to dress so smartly because people would think she was a secretary. She managed to negotiate a day a week to do her own research and secured much sought after Royal Society funding to support it.For decades, Carol felt insecure about having a degree from a further education college, which she achieved by studying part-time for seven years while working at Pfizer; but now Carol is proud of her unconventional route into academia and actively recruits students to her lab from a wide range of different backgrounds.In her hands, mass spectrometry has been transformed from a routine technique for checking what chemicals are present in, say an antibiotic, into a powerful research tool for drug development. Her motto when doing experiments is, 'it's not working yet' and she's happy to risk drilling into this hugely expensive machine to try and get it to do what she wants.Producer: Anna Buckley.

In October 2013, Jeremy Farrar was appointed Director of the Wellcome Trust - UK's largest medical research funding charity. The Trust funded �750 million's worth of health-related research - about the same as the government's Medical Research Council. This means Jeremy Farrar is a major figure in British science. Since 1996, the doctor and clinical scientist had run the Wellcome-funded Oxford University Clinical Research Unit in Ho Chi Minh City in Vietnam - a British-Vietnamese collaboration specialising in infectious diseases such as malaria, HIV, TB and avian flu. He lost close friends and colleagues when the SARS pandemic took off in East Asia in 2003, and dealt with the first cases of the dangerous H5N1 bird flu when it arrived in Vietnam the following here. In conversation with Jim Al-Khalili, Dr Farrar talks about the personal and professional impact of those experiences and of his feelings of impotence as a doctor treating HIV/AIDS patients as a junior doctor in London in 1980s. With his international perspective and his hands-on experience of the deadly potential of infectious diseases, he talks to Jim about the great health challenges faced by the world in the coming decades.
